Another option could be Black Widow. She's very good at adapting to new situations and using her skills in different ways. For Percy, who is coming from a very different world, she could teach him how to be stealthy and use his powers in a more covert way. She could also help him with understanding the political side of the Avengers, like dealing with government agencies and such, which Percy may not be used to in his world of demigods.
The story might start with the Avengers realizing they need someone with Percy's unique skills. They find him through some magical or technological means. Once recruited, Percy would have to adjust to the high - tech world of the Avengers. He'd bring his sense of humor and loyalty from the Percy Jackson universe. There could be some really cool fight scenes where Percy's powers blend with the Avengers' powers in unexpected ways.
Well, initially, the Avengers would be quite skeptical. I mean, they deal with high - tech and super - soldier stuff. But once Percy shows what he can do, like summoning a giant sea monster to help in a battle, they'd start to see the value. Iron Man would likely try to find a scientific explanation for Percy's powers and might even try to replicate them in some way. Captain America would appreciate Percy's courage and how he uses his powers for good, just like he does with his own abilities.
Percy would probably be very confused at first. He's used to dealing with threats from the world of Greek mythology, not superheroes like the Avengers. But once he realizes he's been kidnapped, he'd likely be angry. He'd try to find a way to escape using his powers, like controlling water to create distractions or even using it to overpower his captors.
In a fanfiction, Percy Jackson and the Avengers' interaction would be complex. Percy comes from a world of gods and monsters, and the Avengers from a world of super - science. At first, there could be misunderstandings. Percy might think the Avengers are too full of themselves, and they might think he's a bit of a wild card. However, as they face challenges together, like a group of mythical beasts invading New York, they'd learn to rely on each other. Percy could use his ability to communicate with sea creatures to gather intelligence, while the Avengers use their powers to fight on land. Their combined efforts would make them a formidable team.
Thor would be the most likely to relate to her on some level, as he comes from a world of gods and magic too. He might see her as an equal in a way. Bruce Banner would be interested in the scientific aspect of how her powers work, if there is any scientific explanation within the context of the fanfiction. And the others like Clint Barton and Wanda Maximoff would be curious about her background and how she ended up in their world.
Percy has his speed and agility. In the fanfiction, he might be able to use his demigod reflexes to dodge all of the Avengers' attacks. He could then quickly move in for a counter - attack. Also, his sword, Riptide, is a powerful weapon. It can cut through almost anything. He could use it to cut through the Avengers' weapons or their defenses if he gets close enough.
I've found that Reddit can be a goldmine for fanfiction, including Percy Jackson and Avengers crossovers. There are specific subreddits where fans post their own works or recommend stories they've read. For example, the r/FanFiction subreddit has a lot of posts about different crossovers. You can also try searching for something like 'Percy Jackson Avengers fanfiction' in the Reddit search bar, and it'll show you relevant threads where people are discussing and sharing their favorite stories.
I think Thor would be really tough. Thor has his hammer, Mjolnir, which gives him the power of lightning. Lightning is a very powerful and destructive force. Percy would have to be very careful not to get hit by it. Also, Thor is a god in the Marvel universe, just like Percy is a demigod in his world. So they are kind of on a similar level in terms of their 'godly' status.
In a fight between Percy Jackson and the Avengers in fanfiction, Percy might have an edge. His ability to control water could be a huge advantage. He could create massive tidal waves or use water to disorient his opponents. However, the Avengers are no pushovers. They've faced some of the toughest villains in the universe. Hulk's brute strength and Black Widow's combat skills could give Percy a run for his money. It really depends on the context and the creativity of the fanfiction writer.
Percy would probably be very angry. He's used to being a hero, not a captive. He might immediately start trying to break free, using his water powers to create distractions or even attack if he feels really threatened.
